Much of what causes our personality takes place in our
Unconscious: thoughts, feelings, wishes, and drives that operate below our level of conscious awareness. We don't consciously know they exist.

What’s in the unconscious mind can be revealed in several ways:

At birth, our personality consists of the Id.
Id: the completely unconscious part of the mind, without morals or logic, driven by two instincts:


The id is made of the battling forces of Eros and Thanatos.

The id is ruled by the
Pleasure Principle: the drive to immediately increase pleasure, reduce tension, and avoid pain.
The id tries to satisfy its needs through:
Primary process thinking: forming a mental image of the object the id desires and satisfying the desire through the mental image.


Ego: the partly conscious part of the mind that organizes behavior, is logical, and makes plans to satisfy the Id in safe, realistic ways. The ego develops in the first few years of life.

Reality Principle: the attempt by the ego to find safe, realistic ways of meeting the needs of the id.

The ego is that part of the personality that adapts the person to the real world:

Over time, society’s demands become accepted as an “internal voice” in the child. This is the superego.

Superego: the moralistic component of personality, that judges one’s actions, thoughts, and feelings according to society’s rules and attempts to reach perfection.
True punishment comes from the superego:

The superego also provides rewards for attempting to be perfect: By adolescence everyone has a personality structure consisting of:

The Ego tries to take care of the Id's needs without causing guilt from the Superego.
Sometimes this is possible. Sometimes it's impossible.
